A DNS lookup is the process of sending a query for a specific domain or IP and getting the record that corresponds to it.
DNS queries happen every single time you access a website or a web-related service since there always must be a server (with its designated IP address) that serves that request.
What is the purpose of a DNS lookup?
This system helps you in finding the IP address of the domain names you entered in your browser so that the browser can connect to the website. This system is called the Domain Name System or DNS for short.
What does DNS lookup mean?
A DNS lookup, in a general sense, is the process by which a DNS record is returned from a DNS server. Interconnected computers, servers and smart phones need to know how to translate the email addresses and domain names people use into meaningful numerical addresses.
How does a DNS request work?
The DNS server can use its own cache of resource record information to answer a query. A DNS server can also query or contact other DNS servers on behalf of the requesting client to fully resolve the name, then send an answer back to the client. This process is known as recursion.
What is the use of reverse lookup zone in DNS?
Reverse Lookup Zones. As mentioned earlier, a reverse lookup zone is an authoritative DNS zone that is used primarily to resolve IP addresses to network resource names. This zone type can be primary, secondary, or Active Directory—integrated.
Is DNS a protocol?
(Although many people think “DNS” stands for “Domain Name Server,” it really stands for “Domain Name System.”) DNS is a protocol within the set of standards for how computers exchange data on the internet and on many private networks, known as the TCP/IP protocol suite.
How do I find out what my DNS is?
The DNS you use
In most other versions of Windows, click on Start, then All Programs, then Accessories, and finally on Command prompt. Type “ipconfig /all” followed by Enter. You’ll get a lot of information. In the midst of all that information, you can see “DNS Servers” listed.
